614 REV. O. P. CAMBRIDGE ON EGYPTIAN SPIDERS. [June 20, 



Upper Egypt. It is a very active spider, and appears to be nearly 

 allied to the Attus frontalis (Walck.) of Europe. 



Attus mendicus, sp. n. 



Adult male, length 2| lines ; adult female, 4 lines. 



The cephalothorax is of a deep brown-black colour, densely 

 clothed with greyish and sandy-grey pubescence, and margined with 

 long white hairs ; the hairs on the ocular area are of a distinctly 

 squamose character, and sometimes form alternate longitudinal stripes 

 of a whitish and sandy brownish-red hue. The fore part of the 

 ocular area is also furnished with a few long curved bristles and 

 bristly hairs ; and the clypeus equals in height the diameter of a 

 fore central eye. 



The eyes are in the usual position, and their colour is dull 

 greenish mother-of-pearl ; the ocular area is scarcely broader than 

 long, but projects forward considerably, and the line formed by the 

 two posterior eyes is equal to that formed by the four anterior ones ; 

 the lateral eyes of the anterior row are removed considerably back- 

 wards, so that, looked at from above and behind, the row is strongly 

 curved, with the curve directed forwards ; the interval between each 

 lateral and the central eye nearest to it is very nearly, if not quite, 

 equal to the diameter of the lateral ; the minute eyes of the middle 

 row are respectively halfway between the laterals of the posterior 

 and anterior rows. 



The legs are strong, moderately long, and of a yellowish colour, 

 indistinctly annulated with brown, furnished with spines, and clothed 

 with hair, chief among which is a more or less dense whitish pubes- 

 cence ; the tibiae, tarsi, and metatarsi of the first pair are dark 

 brown. The femora of the same pair are somewhat tumid on the 

 outer sides, rather beneath the fore extremity, where they have also 

 a conspicuous double fringe of dark bristly hairs ; their relative 

 length appears to be 4, 3, 1, 2 ; but the difference is not very great ; 

 beneath the terminal claws of each tarsus is a black scopula, or 

 brush of hairs. 



The palpi are yellow, thickly fringed above and on each side with 

 long, curved, white, bristly hairs, among which are a few black 

 bristles ; the cubital and radial joints are very short, but of 

 about equal length ; and the latter does not appear to have any 

 apophysis at its outer extremity. The digital joint is equal to the 

 radial and cubital joints together, and of an oblong oval form, 

 truncated at its fore extremity ; it is of a deep brown colour, clothed 

 with long whitish bristles and hairs. The palpal organs are very 

 large, but of simple structure, and of a somewhat globularly oval 

 form ; they are nearly black in colour, and extend backwards and 

 outwards beneath the radial joint. 



The falces are small, directed backwards, and, from the promi- 

 nence of the ocular area, placed far back beneath the fore part of the 

 cephalothorax ; they are of a dark yellow-brown colour, clothed with 

 hairs. 



The abdomen is of a broadish oval form, dark black-brown,
